Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

Setup guide (opens in a new tab)QuickBooks Online holds the billing record and Beehiiv holds the subscriber record, and the two rarely agree on their own. Connecting them means a paid invoice or a new customer in QuickBooks Online can set a subscriber's tier, tag or status in Beehiiv, and a new Beehiiv subscriber can arrive in QuickBooks Online as a customer ready to bill.

Questions
Beehiiv and QuickBooks Online, answered
How does the agent match a QuickBooks Online customer to the right Beehiiv subscriber?
It uses the email on the QuickBooks record and calls Beehiiv's get subscription by email, so the update lands on a subscriber that actually exists. You can have it stop when no subscription comes back, or create one with create subscription instead.
Can a paid invoice in QuickBooks Online change someone's newsletter tier in Beehiiv?
Yes — the new paid invoice trigger can feed Beehiiv's update subscription by email, which changes tier, status or custom fields. The agent tests every scenario, including invoices whose billing email has no matching Beehiiv subscription.
What can start an automation from Beehiiv?
Any of Beehiiv's 8 triggers in the catalog, including New subscriber to publication, New unsubscriber to publication, List automations and List newsletter lists. Describe the moment in plain language and your agent picks the right one.
What can your agent do in QuickBooks Online when something happens in Beehiiv?
Any of QuickBooks Online's 45 actions, including Create credit memo, Create customer, Get invoice by ID and Create account. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from QuickBooks Online to Beehiiv?
Yes. When something happens in QuickBooks Online, your agent can act in Beehiiv too. This page covers both directions: QuickBooks Online's triggers and Beehiiv's actions are listed here as well.
Do I have to build a connector for Beehiiv or QuickBooks Online?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Beehiiv and QuickBooks Online without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
